Mediawiki installation and configuration
Be careful, you have to create main page (there’s no way to import main page with xml import feature). Copy main page source code from the old mediawiki server!

yum install httpd php php-gd php-xml postgresql postgresql-server php-pgsql

chkconfig --level 345 postgresql on
chkconfig --level 345 httpd on

service postgresql initdb

vi /var/lib/pgsql/data/postgresql.conf
listen_addresses = 'localhost'
port = 5432

cat << _EOT >> /var/lib/pgsql/data/pg_hba.conf
local all postgres trust
local all all md5
host all all md5
host all all ::1/128 md5

service postgresql start

su - postgres

psql -c "alter user postgres with password 'password'"

semanage boolean -m --on httpd_can_network_connect_db

vi /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

service httpd restart

tar zxvf mediawiki-1.24.1.tar.gz

vi /etc/httpd/conf.d/mediawiki.conf
